I'm in the process of adapting the Age of Worms to the Realms, and while I really appreciate the fact that Eric and Pazio went to the trouble of creating the Overload supliment, I just didn't feel it fit "my Realms."
My players would have a lot of trouble believing the AoW as described in the FR portion of the Overload - especially in the changes to Daggerford. Unfortunatly, this is an area in the Realms that my players have adventured around in ever since the N4 module days. They are very familiar with the 'canon' descriptions of the region, and have actually helped shape the region in my version of the Realms. Changing Daggerford so significantly just won't "feel right."
What I decided to do was follow Eric's advise to another poster over on the WotC boards vice and stick the module "somewhere in the middle of nowhere" in the Realms. I chose the Moonsea. It has the hard-edge, down-on-your-luck, everyone's out for themselves attitude needed for running Diamond Lake just as it's described in the Dungeon magazine adventurers.
For those of you familiar with the Realms, I placed Diamond Lake northeast from Phlan - about ten mile northeast of the far eastern edge of the Dragonspine Mountains. Neither the town, lake or the river draining from the lake appear on any FR maps, which is fine for me. The place is really just a small backwater place. This way, I can still even call the place Diamond Lake (it's a reasonable Damarain translation of the original dwarven name for the place).
The cairns are located SE of Diamond Lake, in the western edge of the Thar. The various cairns & tombs were built by a number of earlier civilizations, including the Eldar Ogers of Thar, the dwarves of several kingdoms, Giants and even some of the early humans of ancient Phlan. Obviously, the Vaati tombs predate them all, but since many of the lesser races copied (as best the could) the architecure of the Vaati, the tomb from the first module won't stand out until the players get into the adventure.
Rather than use the Vaati as part of the Djinn who founded Calisham (as Eric suggests), I've decided to say that they were followers of Akadi (Godess of Elemental Air) and say that they have struggled against the evil forces of Auril (Godess of Winter) for centuries in the windswept plains of the Tortured Lands to the north.
Thus, I won't use the AoW hooks for the Rod of Seven Parts. Instead, I'll make the segment of the rod a Legacy Weapon for Akadi's faithful. It can grow in power as they progress through the AP.
Blackwall Keep is a castle on the northern border of the lizardman infested Glumpen Swamp, which is northeast of Phlan. It's manned by soldiers from Phlan, and basicaly serves as a rest stop for ore caravans from Glister and the western Dragonspine mountains heading south.
The "Free City" will be Phlan. All I had to do is adjust my map of Phlan to include an arena, which I'm actually thinking about putting in the ruined ward formerly occupied by Castle Velajio. That will also allow me to tie in Moander and the Pools of Radiance to the plot, which I intended to do anyway.
I've also changed the three Gods that Eric recommended using in the Overload. I did this mostly because I wanted to use Moander (the God of Rot and Decay) in the AP. He's an old favorite of mine, and I haven't used him in a long time. He should be an unpleasant surprise for my players.
To go along with Moander (as Nerull), I'm using Gargos (as Hexor) and Bhaal (as Erythnul). All three of these gods are either dead or waning in the modern Realms, so this joint venture represents a gamble of the three faiths to re-establish themselves as movers and shakers.
The only changes I forsee making in the Kyuss-related material is that the worms from the Kyuss Zombies are green, rotting earthworms rather than segmented flatworms. This is a outward sign that Moander is involved in the plot.
That's about as far as I've gotten with the conversion, but I thought I'd see if you folks had any comments or saw any problems with what I've done so far. Let me know what you folks think of these ideas and feel free to poke holes in what I've said here. I want to make this adapttation as tight as possible,and I'd welcome your help.
